| 摘 要： | 目的探讨影响CT导向下经皮纵隔病变自动切割活检(automated cutting needle biopsy,ACNB)准确性的相关影响因素。资料与方法回顾性分析89例采用CT导向下经皮纵隔病变ACNB的患者资料,以最终诊断结果为金标准,计算穿刺活检诊断恶性病变的敏感性、特异性、阳性预测值、阴性预测值及准确性。应用χ2检验分析不同病变部位、大小、良、恶性及穿刺次数等对穿刺活检准确性的影响。结果 89例纵隔病变穿刺活检患者中有80例与最终诊断结果相符,穿刺活检诊断恶性病变的敏感性、特异性、阳性预测值、阴性预测值、准确性及其95%可信区间分别为90.5%(84.4%～96.6%)、86.7%(79.6%～93.8%)、97.1%(93.6%～100%)、65.0%(55.0%～75.0%)、89.9%(83.6%～96.2%)。经统计学分析,经皮纵隔病变ACNB活检准确性与病灶大小、穿刺次数有统计学意义,穿刺层面病灶越大,活检准确性越高;穿刺次数为3次组活检准确性高于<3次组,而与>3次组无明显差异。结论 CT导向下经皮纵隔病变ACNB对纵隔病变定性诊断准确性高且安全,纵隔病变大小及活检次数可影响活检诊断的准确...

| Abstract: | Objective To explore the diagnostic accuracy of CT guided percutaneous automated cutting needle biopsy(ACNB) in mediastinal masses.Materials and Methods Eighty nine patients with mediastinal masses who underwent ACNB between 2005 and 2010 were retrospectively analyzed.The histopathological results were regarded as golden standard and final diagnosis.The diagnostic accuracy,sensitivity,specificity,positive predictive value(PPV) and negative predictive value(NPV) of ACNB for malignant mediastinal masses were ... |
